How to assign multiple keypresses

[hooliowobbits]

Hi mate, thanks heaps for your efforts, I really appreciate what you have done and thanks so much for taking the time to document it and and publish it; it's awesome.

I was able to get ratslap working OK, and If i assign a single button it works fine; here i assign the number 5 key to mouse button 5:

$ ./ratslap --modify F4 --g5 5

    Setting button 5: 5

As per your example I can use the + modifier OK:

./ratslap --modify F4 --g5 LeftCtrl+TAB

However if i use the + syntax to assign both numbers 5 and 6 to mouse button 5 i get an error:

./ratslap --modify F4 --g5 5+6

No problems at all, thank YOU for trying it out and the kind words :)

Unfortunately, you are limited to ONE key with modifiers. The modifiers are hard coded ( as per --listkeys ):

• LeftCtrl
• LeftShift
• LeftAlt
• Super_L
• RightCtrl
• RightShift
• RightAlt
• Super_R

Unfortunately this is a limitation of the firmware. The only way around this were if you had a running process that would capture a known combo and then produce the keys.

This could be achieved using xbindkeys(1) to detect the combo, then xdotool to type the keys.

I had explored xbindkeys + xdotool already and I was able to get them to work (see below); however they did not work within the proton/steam-play game "Grim Dawn.exe". Getting combos/macros working into these games is apparently non trivial. I'm still exploring other options.

xbindkeys + xdotool use with ratslap setup g300s to send Button6 with ratslap

$./ratslap -mf4 --g5 Button6

to test what that actually did, I can identify the button with xev. it appears however that xev can't detect the buttons properly if xbindkeys is running, so we kill it first.

$ killall xbindkeys
$ xev | grep -i button

then click inside the little xev test window and see what i get on the console

ButtonPress event, serial 38, synthetic NO, window 0x2400001,
    state 0x0, button 8, same_screen YES
ButtonRelease event, serial 38, synthetic NO, window 0x2400001,
    state 0x0, button 8, same_screen YES

curious it calls that button 8 when i coded it as Button6. regardless.. configure .xbindkeysrc as follows:

# Button 8
"xdotool key 5 6"
b:8

kill any xbindkeys and restart it

$ killall xbindkeys
$ xbindkeys -f ~/.xbindkeysrc

and now when i press my g5 button 3 times, i get

565656

I would try a key vs a mouse button too - might make a difference with the above and/or:

Does xmodmap show a one for one mapping?

xmodmap -pp

Mouse buttons work very different to keys and in fact the mouse even presents as different devices to deliver these events. I would certainly try keys as well, just in case. It doesn't even have to be one you have on your keyboard, eg F13
